I guess I'd have to say that engine performance is ultimately a
little easier to quantify than suspension performamance. Once you've
set up the Engine X with a new cam, a chassis or engine dyno can tell
you exactly what you've done to the horsepower or torque curves...Of
course there would be a lot of setup dyno time in determining the
right fuel system setup, cam timing, and any other variable you would
change to maximise performance with that cam. Then you could look at
the drive train ratios in relation to the power curve and type of
driving you are doing to stay in the power band. A multi-variable
problem can be a real bear...
